1 box chocolate graham cracker crumbs                  1 Tbsp. flour

4 oz. walnut pieces                                                ¼ stick butter, softened

6 oz. chocolate chips (or any flavor)                        (dash of oil if needed)

8 oz. whipped cream cheese                                   1 tsp. vanilla

1 cups sugar                                                         3 eggs

Mix graham cracker crumbs, walnut and chocolate chips in a large Ziploc bag.  Pour out what you need (about ½) in a 9” spring form pan to make a crust, pressing evenly in bottom of pan and refrigerate the balance for another use.  Bake at 350 degrees for 5-6 minutes.   Whip cream cheese and whipped cream cheese until fluffy.  Add sugar, flour, butter, sour cream, vanilla and eggs one at a time.  Pour over crust and bake at 350 for approximately 40 minutes.  Leave in oven after turning off.
